accept callback function for user requests as a parameter for apimock

[asnov]

Hi @gstroup ,

I use apimock like this:

var ApiMocker = require("apimocker");
var apiMocker = ApiMocker.createServer(options)
    .setConfigFile(__dirname + '/config.json')
    .start(port, function() {/* callback for establish connection */});

Now I faced the task to use TimeStamp in responses because of the strict security restrictions of the .Net WCF library.

Is it possible to add response callback function to apimock?

I think this is a good idea in general. @ztsmith suggested that it might be a better idea to expose the express middleware, then you could add a middleware function to do whatever you like. Would that solve your problem?? Let me know what you think.

[asnov]

Yes, that would solve my task. How do you think to expose the express middleware?

Please take a look at the latest version 0.4.9. I added support for custom middleware functions, that should solve this problem. Please let me know what you think! @tedvanderveen @asnov @ztsmith

[asnov]

Great! It is not so cute as to add a separate method to use chaining like this:

ApiMocker.createServer().setConfigFile().addmiddleware().start();

but it is works. It solves my task. Thank you!

[ztsmith]

Cool!

This makes me think.... if the config file was a JS file, we could define custom functions and middleware and specify them in the config. I think this would unlock an endless array of configuration options.

@asnov - yes, I thought of adding a simple "addMiddleware()" function, but I decided to expose the entire array. This way, people have full control over the order of middleware functions. But, it would probably make sense to add a simple "addMiddleware()" function as well.

@ztsmith - I was also thinking how it would be great to define custom functions right in the config file. But I wasn't sure how the config file would parse then... we'd need to do some more testing on that. But I like the idea.

@gstroup what is the status of this? Thanks!

[gstroup]

@tedvanderveen At the moment, the entire "middlewares" array is exposed, so you can add a customer middleware function anywhere in the pipeline. https://github.com/gstroup/apimocker#adding-custom-middleware Does that meet your needs?

Or would you prefer to have a simple addMiddleware() function instead? That would require a small code change.
